This one is similar to the existing signatures 45415 and 45416. The only difference is that is uses the StdOleLink Moniker as opposed to the Composite
Moiker. There are 2 versions for each rule. The first one is without using PCRE. The samples I worked with had the moniker slightly manipulated, and PCRE was a perfect fit. Pcaps available for these.

Note that the sample documents contain multiple exploits and not just one.
